The temperature of a liquid in an experiment changes by -10.4F from the beginning of the experiment to the first check. After ma

king some adjustments, the scientist checks the temperature again later and finds that it is 17.7F, which is 1/3 what it was at the time of the first check. What was the initial temperature of the liquid?

Answer:

  63.5F

Step-by-step explanation:

Let x represent the temperature at the start of the experiment. Then the temperature at first check is (x -10.4F). The temperature at the second check is 1/3 that value, and is said to be 17.7F. This lets us write the equation ...

  1/3(x -10.4F) = 17.7F

Multiplying by 3 gives ...

  x -10.4F = 53.1F

  x = 63.5F . . . . . . add 10.4F

The initial temperature of the liquid was 63.5F.

<em>Additional comment</em>

Temperature is measured on an "interval scale." On such a scale, the value 0 is located arbitrarily. Concepts such as "1/3 of the temperature" have no meaning on such a scale. Here, we have to ignore that fact and assume the problem is about the numbers, not about any real temperature relationship in thermodynamic terms.

What is the relationship between angle BAC and angle BOC?
Basile [38]

In this problem, an angle like angle BAC where the vertices like on the circle itself is called the inscribed angle.

While angle BOC, where O is the center of the circle, is called the central angle.

Using  Proposition III.20 from Euclid's Elements, this is called the Inscribed Angle Theorem  wherein:

∠BOC = 2∠BAC

or ∠BOC / 2 = ∠<span>BAC</span>
